Okay, let me be more specific here. The word "occult," which literally means "hidden," has come to be a synonym for "supernatural" or "paranormal." Magic (the art of changing things with the power of the mind) is therefore considered to be "occult" by mainstream culture. However, it is believed by a number of people that magick (spelled with a k to differentiate from David Copperfield's act) can be practiced by anyone who puts forth the effort, and fits perfectly within natural laws, albeit laws our scientists haven't discovered yet. Therefore, it cannot rightly be called supernatural, as it is not violating any of the laws of nature. In fact, when you use the "power of positive thinking," you are thought to be using a kind of magick.
